What NestWise does that this doesn’t
- Keeps your loan on your Housing page, and puts its repayment into your Bills and Cashflow.
- Loads your saved loan into the repayment calculator and compares any rate, extra repayment or offset with it.
- When the Reserve Bank of Australia (RBA) moves the cash rate and your variable loan has not caught up, says so on Home, with what it may mean for your repayment.
- Records a rate change when your lender sends one, and keeps a dated history of your rate.
- Groups the loan with its property — what the property is worth and your equity, once you add its value.
